I was also thinking that I don't want to rule out any class of theory, even if I think the likelihood is extremely small of them being useful.

But apart from dumb stuff like bigfoot or fairies, there may be one exception, which is basically any theory that would lead to a million different translations if done by a million different people. Like any substitution theory with interpretative steps. That's just creative writing.
